IUG: Revived

This is a remake of Incremental Universe Growth by -Danielt- and me (Quasitruncated Hexahedron). That was never finished as Replit shut down the original .repl.co domains on January 1st, 2024. I did move it to GitHub (of which my account there has since been terminated - thankfully, I'm 13 now, don't worry), but that eventually ended following the insane backlash from the game's poor reception on Galaxy, an incremental sharing platform, mainly over the extremely long timewalls and poor balancing.

That was in turn the spiritual successor to Universe Expander, a Scratch incremental made by the same person. The name was changed for already being taken.

Credit goes to the following people for parts of this project:

Patashu, for break_eternity.js
MathCookie, for both Eternal Notations and The 2048 Power Compendium, of which the latter's save codes were used as inspiration for how text saves work in this game.

Latest Version: v0.3.0a [August 31st, 2025, 00:55 AM GMT]

Added yet another softcap to dark matter gain to try to prevent getting to NaN values at this point
Added additional cost scaling to dark matter buyable 3
Intentionally keeping challenge 7 impossible so I can use it for the "Antimatter ?????????" listed below

Coming soon:

Subjective Milestones
Antimatter ?????????

v0.1.0 [June 2nd, 2024, 09:49 PM GMT] (yes, really)

Initial version
Only universe size and upgrade 1

The main upgrades all generally have an immediate impact on your universe growth, or atleast through another main upgrade. Main upgrades are numbered going top to bottom, left to right, so +x m/s is upgrade 1, ×x m/s is upgrade 2, etc. Upgrade 1 cost scales very little, and when combined with upgrade 3 you can buy it over and over again - please do not do all of this manually! You could buy upgrade 1 up to about 200 times or so, you will very likely get hand injuries.

In addition, there is also antimatter. This is a softcap starting at 1,000,000m, and (at least at the start), there's not much you can do to fight back.

Dimensions reset progress for an additional boost, with it boosting your universe growth ^sqrt(# of dims). Each extra dimension makes it such that you can get back to where the previous dimension left off fairly quickly.

Automation is fairly self-explanitory: does what would take 1000 clicks with only 1 click or entirely hands-free. With the exception of the first automation upgrade, which instead unlocks being able to buying upgrade 1 in bulk, automation upgrades unlock a corresponding automator. These can then be disabled or re-enabled at will.

Note: The second automator, Automatically buy upgrades 1 and 3 in bulk, will only allot 1/100 of your universe size to upgrade 1 and 1/25 to upgrade 3 - this way it doesn't just consume everything with no chance to buy anything else whilst its on.

Dark Matter is a full prestige layer - you reset, not for a boost directly, but in a currency which gives a boost. Actually, why am I just saying things you should already know here?

Challenges... exist. They provide a boost and can be beaten five times, and... that's about it. Also: if it wasn't already clear from that description, then challenge 7 is designed as such to be a joke to complete at this point. It will be possible later on.

Objects... ok does this REALLY need to exist?! You can't even access this yet anyways.

Either progression or things you might want to go for, all for only bragging rights

You have 0 dark matter, boosting your universe growth ^1

You have 0 challenge completion(s), giving a ^1 boost to your dark matter boost.
All challenges disable both dark matter upgrades and can be completed up to five times.

You have 0 object(s), boosting your dark matter growth ×1
